a What weather is he likely to face over the next couple of weeks, assuming he continues?
b Are the routes across the Appalachians switchbacks with sustained but not awful inclines, or straight up and over?
c From what I've gathered your Interstates are like our motorways and have a no pedestrians rule (on a state by state basis?) - do they have a minimum speed limit for vehicles?
d Where do these attempts usually end in NY? What alternatives does he have to Times Square? I laughed when someone said they wouldn't be able to roll into NYC at 3mph - I thought the traffic was usually gridlocked anyway?!
a Hot and probably quite humid, at least compared to the UK.
b The roads I have driven go straight over but generally at gaps / through valleys rather than the highest point. The Appalachians aren't really that high anyway, we are not talking about the Rocky Mountains or the Alps.
c Yes, Interstates are like motorways and are generally restricted to certain types of traffic. Some states I think have minimum speed limits. Driving and running at 5mph on the busy East coast Interstates would be a quick way to bring this run to an abrupt and messy end!
d Don't see why he has to enter NYC at all. It could end anywhere on the East Coast as long as he has run the minimum distance required for the record.
